The soil in the Village Sinar Sabungan have acidicsoil pH, organic matter content is moderate, the ability of the cation exchange capacity of themedium, which is very low base saturation while high levels of total soil ferrum. The soil fertility inthe village of Lumban Lobu have acidic soil pH, organic matter content is moderate, the ability ofthe cation exchange capacity of the medium, which is very low base saturation while high levels oftotal soil ferrum.Keyword: Sihiong village soil profile, Sinar Sabungan village soil profile, Lumban Lobu villagesoil profile
